Theaws-serverless-java-container makes it easy to run Java applications written with frameworks such asSpring,Spring Boot,Apache Struts,Jersey, orSpark inAWS Lambda.

Serverless Java Container natively supports API Gateway's proxy integration models for requests and responses, you can create and inject custom models for methods that use custom mappings.

Currently the following versions are maintained:

Follow the quick start guides inour wiki to integrate Serverless Java Container with your project:

• Spring quick start
• Spring Boot 2 quick start
• Spring Boot 3 quick start
• Apache Struts quick start
• Jersey quick start
• Spark quick start

Below is the most basic AWS Lambda handler example that launches a Spring application. You can also take a look at thesamples in this repository, our main wiki page includes astep-by-step guide on how to deploy the various sample applications using Maven andSAM.
